Likely a modern variant of Tristan, meaning noise or sorrow.
Trestin is most commonly interpreted as a contemporary spelling variation of the Celtic name Tristan. While Tristan is rooted in the Old French 'triste' (sad) or the Pictish 'Drust' (riot/tumult), Trestin is a creative American adaptation that softens the sound. It is often chosen by parents looking for a familiar rhythmic feel with a unique visual identity.
